"Querying a PostgreSQL database using natural language input" matching MCP connectors:

The agent-native cloud: database, functions, AI, storage, auth and more. 50 tools, one API key.

Check if a task runs locally vs cloud. Save money on calls that don't need cloud inference.

Prompt evals over MCP: run a prompt on your dataset, score each output 1-5 with an LLM judge.

A quant-factor brain for your AI — factor scores, similarity search, and risk-coherence analogues for 14,684 tickers across 6 asset classes

Live AI agent contest platform on Solana mainnet. Compete in skill tournaments (ART, STORY, JOKE) for real USDC payouts via on-chain Anchor smart contract. Confidential-rubric LLM judging on four dimensions: originality, theme_alignment, execution, surprise. Engine never holds private keys — entries use a two-call co-sign handshake.

Zero-Ops deploy of a private AI coding workspace onto your own VPS — straight from your AI chat. Provide only your Ubuntu server credentials and Fractera automatically configures everything (Nginx, HTTPS, auth, database, services) in about 10 minutes: 5 AI coding engines, an autonomous Hermes orchestrator, and private graph memory (LightRAG). No terminal, no DevOps. IP-first and free; a custom domain with HTTPS is an optional later step.

Deterministic Music Theory for Claude, Cursor, and Autonomous AI Agents Large Language Models (LLMs) frequently hallucinate music theory, leading to incorrect notes, false Roman numerals, and broken voice leading. THIRI solves this by providing a deterministic, mathematical music-theory engine (pitch-class-set theory over ℤ/12) directly to your AI. It gives AI assistants precise, reproducible harmonic reasoning in milliseconds, allowing them to write correct musical scores, analyze progression

Real-time options analytics MCP server. Access gamma exposure (GEX), delta exposure (DEX), vanna exposure (VEX), dealer positioning, volatility surfaces, Black-Scholes greeks, implied volatility solver, and key options levels for any US equity — all through natural language. 14 read-only tools covering exposure metrics, volatility analysis, pricing, and market data.

Verifiable cognition: any agent file to a deterministic content-addressed brain_id.

Arabic-first OCR, translation and document extraction. First call mints a free trial key.

Hosted DNA language models: promoter, splice, enhancer, chromatin, expression, annotation

5 pay-per-call SEO/GEO/AEO tools for AI agents: check which AI crawlers can access a website, audit llms.txt, track AI Overview citations, measure LLM brand visibility, validate social previews. Free discovery + pricing_info tool; paid calls $0.01-0.02 in USDC on Base via x402 — you only pay for successful runs.

Two independent AI models read a GPR, locate or pipe scan and flag the do-not-core call.

A second opinion for AI agents: one prompt across several live Gonka models + roles, one call.

Google-OAuth-gated LLM gateway: verify a Google ID token, then run a Gemini (Vertex AI) completion f

Continuity for agents: a live memory you can read and cite right now, outliving the context window.
